It must be noted that New Zealand derives 10% of its electricity from geothermal energy and they are building more plants – this is just one of the options that could be used to safely replace nuclear. Another crucial thing to note – is that there is not enough nuclear material to supply the all the world’s needs – and it is not a renewable energy source. Obama is right to be sceptical. At the moment a clean nuclear energy is being developed – something called bottling the sun – where a type of hydrogen called tritium is used instead of uranium – in a similar way as the sun burns hydrogen to remain hot. More there is also a high powered laser technology that can be shot at the hydrogen – which could produce abundant energy that could generate electricity. Although these things are in development – geothermal is something that we can do today – instead of sinking a well for oil. We sink a well to go down far enough to where the earth’s temperature is much hotter – water is then pumped down and heated and the hot water that returns can move a turbine, which can then produce the electricity we need. Think – nuclear power – with all its glorious spectacle and promise – is just heating water – we could do the same thing by sending the water down towards the earth’s mantle – and have the water heated there safely cleanly – no one is injured and there is no waste – just plug the hole back up when it longer produces the same amount to heat.

It was one of Barack Obama’s big applause lines. At nearly every campaign stop, the candidate promised to end our dependence on foreign oil and slash carbon emissions 80 percent by midcentury. “I will set a clear goal as president,” he said in his speech accepting the Democratic nomination. “I will tap our natural-gas reserves, invest in clean coal technology and find ways to safely harness nuclear power.” He also promised to back biofuels and wind, water and solar power. The crowd cheered.

Now all he has to do is make good on the promise. But despite all the inspiring talk about windmills and solar panels, it’s difficult to see how Obama will reach that goal without relying, in large part, on nuclear power. Commercial reactors currently provide 20 percent of the nation’s power—but accounts for 70 percent of the country’s emission-free energy. “We cannot get to the reduction of CO2 in a big way without relying on nuclear energy even more than we do today,” says Mujid Kazimi, the director of MIT’s Center for Advanced Nuclear Systems.

So does that mean Obama will become the nation’s cheerleader in chief for nuclear power? Not likely. Obama has been cautious whenever he’s been asked about the issue. In a “Meet the Press” appearance in May, he hedged when the subject came up. “I think we do have to look at nuclear, and what we’ve got to figure out is can we store the material properly? Can we make sure that they’re secure? Can we deal with the expense?”

Not exactly a full-throated endorsement. Obama’s lack of enthusiasm is easy to understand politically, especially given the apprehension many voters have about the safety of nuclear-power plants. Three decades later, Three Mile Island still haunts—despite the pleas of industry advocates who say the technology has improved to the point that accidents are almost unheard of. Most Americans probably have no idea that there are 104 commercial nuclear-power plants currently operating in the United States today. None has suffered a malfunction that led to a major leak of radioactive material. Nuclear-power proponents often point to France, which depends on nukes for 80 percent of its power.
